"We have come here with a fairly comprehensive aero kit and happily that all seems to be working as expected," explained Trackside Engineering Director, Andrew Shovlin.
"Both drivers were quite happy with the car from the early runs of FP1 and we haven't had to make big changes to get it in the window.
"FP2 was more tricky, the balance wasn't quite as good and it didn't feel like we got the most out of the UltraSoft tyre on a single lap, Lewis even set his fastest lap on the Soft.
"Valtteri was happy with his car on the long run and his pace is encouraging. Lewis wasn't comfortable on the UltraSoft on the long run, but the Soft tyre looked strong.
"We normally see Ferrari take a big step forward from Friday to Saturday so we are not paying a lot of attention to the lap times from today, rather we will try and work on the issues that both drivers have highlighted and see if we can find a bit of pace for tomorrow.
"It's always a close grid at this track so getting every little detail right will be important."
